I always thought it would make a fine animated movie, or maybe even a TV series. Given The Clone Wars on the tube, that's not beyond the realm of possibility. And the original actors could do the voices, which would be a selling point, I'd think.
Of course, I wouldn't make a nickel from such a project. I got paid well for the book, but don't have a piece of anything else; still, I'd love to see it.
Disney needs to make its money back, and Shadows was, if I do say so myself, a great story, everybody but Han in it, and a nasty villain that Princess Leia knees in the nuts.
Are you listening, Mickey?
